I had a power outage and my docker containers got killed. After restarting them, Grafana is very
slow and I get a lot of these messages in the logs:
t=2019-04-21T16:28:24+0000 lvl=eror msg="Failed to update last_seen_at" logger=context userId=1 orgId=1 uname=admin error="database is locked"
I also cannot save the dashboard. I suspect there are some stale locks in place?
Can anyone tell me how I can fix this?
Thank you very much!
